GWENT - Northern Realms vs Skellige

Actually made a blunder with last card placement on 2-nd round. Should have placed last card on melee row to get instant boost. So if you're very expirienced in this game feel free to write down in commentary how could i played this match better. I'm really loved gwent in witcher 3. So i want to better understand how to play Online Gwent. So maybe in future i will be winning some gwent tournaments, and your advices would lie in the basement of my tower of gwent glory =)
